I had heard that TDI's, and VW's in general, are a maintenance nightmare. Both in cost and just finding a dealer. Also, I found out this weekend that my CTD will stomp a mudhole in a TDI from a stop light. Plus, TDI's, let's face it, they're unbelievably ugly. CTD's on the other hand are a darn good looking car with a vastly better better interior.
